Modern cities are exposed to various dangers due to advanced technologies and advanced technologies. As a result, the desire for citizen's safety is increasing day by day, and the sense of insecurity is reaching extreme. In order to respond to the paradigm of the era for safety, the government has stipulated that crisis management manuals are prepared and operated according to the type of disaster. In this research, before preparing and managing crisis management manuals, we classify the types of disasters that can occur in A local authority, establish priorities of types of disasters to be managed with priority, We will try to utilize it as a basic material for the creation and management of.

The principle of energy dissipation technology is to dissipate or absorb the seismic energy input through the deformation or velocity change of dampers installed in the main structure of high-rise buildings, so as to reduce the seismic response of the buildings. With the development of energy dissipation technology, recognized as an effective and new measurement for reducing seismic effects, its application in high-rise buildings has become more and more popular. The appropriate energy dissipation devices suitable for high-rise buildings are introduced in this paper. The effectiveness of energy-dissipation technology for reducing the seismic response of high-rise buildings with various structural forms is demonstrated with a number of actual examples of high-rise buildings equipped with various energy dissipation devices.

본 논문에서는 재난안전 대비 현장훈련시스템을 개발하기 위하여 현황을 분석하는 것이 목적이다. 미국, 일본의 재난대응훈련의 특징은 우리나라와 같이 평가지표 틀에 맞춘 시나리오를 개발하지 않고 있으며 시나리오 구성도 세분화하지 않고 단지 상황 설정과 대응 메시지, 돌발 메시지 등으로 위기대응 능력을 평가하고 있다는 것이다. 에너지산업 현장용 재난대비 훈련시스템 개발 및 구축은 국가안전 관리 측면에서도 매우 중요하다. 국가 차원의 종합 재난대응 및 인프라 제공을 위한 다수의 정보화사업이 추진되고 있으나 재난 정보를 활용한 사전 예방, 신속한 상황 전파, 정보 공동 활용 및 대응 미진에 대한 종합적 진단이 필요하다.

This study selected the national park area of Mt. Seorak in Inje-gun, Gangwon-do, where a lot of debris flow occurred due to the heavy rainfall and conducted a field survey. In addition, topographic spatial data were constructed using the GIS technique to analyze watershed characteristics. For the construction of terrain data after the disaster, the debris flow occurrence section was scanned and the 3D topographic data was constructed using the terrestrial LiDAR. LiDAR terrain data are compared to digital maps(before disaster) to assess precision and topographic data before and after the disaster were compared and analyzed. Debris flow diffusion area was calculated using FLO-2D model and compared debris flow occurred section.

We reconstructed the community disaster risk and patterns of damage magnitude using 'Annual Report of National Disaster Data'. And we developed the inspection index for damage reduction capacity of each facility or each damage prevention measure. The inspection indices include climatic and hydrological vulnerabilities, and disaster probability components. Also we considered all indices and components for DB construction on the GIS system. Then we constructed 'Inspection for Safety Degree of Community System(ISDCS)' according to the facility's criteria from the combination of damage reduction capacity of facility and damage magnitude. The safety index has designed a system that encourages communities to carry out a list of activities in the raw from natural disaster. The activities ultimately saves lives, reduce property damage, and protect disaster facilities. Damage patterns were also analyzed according to damage type using pattern analysis and GIS.

This paper was concerned with the nonlinear analysis on the overall stability of H-type honeycombed composite column with rectangular concrete-filled steel tube flanges (STHCC). The nonlinear analysis was performed using ABAQUS, a commercially available finite element (FE) program. Nonlinear buckling analysis was carried out by inducing the first buckling mode shape of the hinged column to the model as the initial imperfection with imperfection amplitude value of L/1000 and importing the simplified constitutive model of steel and nonlinear constitutive model of concrete considering hoop effect. Close agreement was shown between the experimental results of 17 concrete-filled steel tube (CFST) specimens and 4 I-beams with top flanges of rectangular concrete-filled steel tube (CFSFB) specimens conducted by former researchers and the predicted results, verifying the correctness of the method of FE analysis. Then, the FE models of 30 STHCC columns were established to investigate the influences of the concrete strength grade, the nominal slenderness ratio, the hoop coefficient and the flange width on the nonlinear stability capacity of SHTCC column. It was found that the hoop coefficient and the nominal slenderness ratio affected the nonlinear stability capacity more significantly. Based on the results of parameter analysis, a formula was proposed to predict the nonlinear stability capacity of STHCC column which laid the foundation of the application of STHCC column in practical engineering.

In the current business environment where dependence on IT has increased rapidly, the risk from disasters or cyber-attacks is also increasing. Business continuity, the ability to continue to provide service in the event of a business disruption caused by a disaster, is essential. In other words, you need to have a plan in place to keep your core business functions uninterrupted with rapid recovery within a predetermined Recovery Time Objective (RTO) and Recovery Point Objective (RPO) time frame. In this paper, we propose a disaster recovery system construction method that can minimize RTO and RPO to ensure business continuity. The system configuration adopts Tier 7 disaster recovery model, synchronous storage replication, hot disaster recovery site, and operation management automation solution. This ensures continuity of core business with virtually no data loss and minimal RTO and RPO.

Purpose: The fields manuals which is managed by the each disaster types are the integrated guideline. When the disaster occurred, all kinds of SOPs which are described in the manual does not need. Therefore, the person in charge is confused which SOP is executed. In this study, we propose the disaster response process model based on the specific disaster situation case. Method: Firstly, we define the disaster situation cases which is mentioned in the field manual, and then, we develop the disaster response process model including indispensible SOPs for the specific disaster situation case. As a verification and feedback process, we apply the model to Safety Korea Exercise scenario. Result: We developed SOP model and disaster response process model reflecting the concept of the disaster situation case. Conclusion: Safety Kore Exercise scenario reflecting the developed model may continuously upgrade the field manual.

In 2005, Urban railway seismic design was introduced in Rep. Of Korea, and many studies on seismic performance evaluation and reinforcement methods were conducted. In accordance with the Enforcement Decree of the Earthquake Disaster Countermeasures Act issued in March 2009, during April 2010 to October 2013, some of local governments established detailed evaluation and reinforcement measures for seismic performance of the urban railway underground structure. Afterwards, the seismic performance reinforcement of the existing urban railway structures was conducted for the sections that a long period of used until the end of 2018, and the reinforcement works are carried out by various methods using the previously studied methods. However, various reinforcing materials and construction methods using have been studied, but the classification research on the construction methods currently applied to reinforcement construction of urban railways is insufficient. The purpose of study is to analysis the cases currently applied to seismic reinforcement construction and to show the characteristics of each construction method, the reasons for its application and problems.
